This piston is intended for motocross machines, specifically for Kawasaki KX 250 models from 2002, 2003, and 2004 (KX250L / KX250M). It is suitable for rebuilds where oversize A is required and where a forged part is desired, often chosen by riders demanding durability and low rotating mass.

Before installation, check the condition of the cylinder and adhere to machining dimensions and manufacturer tolerances. Checking clearances, using a clean installation, and, if in doubt, consulting a specialist will ensure reliable operation of the piston-cylinder assembly.
